A nocturnal activity pattern is central to almost all hypotheses on the adaptive origins of primates but this view has been challenged recently on the basis of variation in the cone opsin genes of nocturnal primates. The diversity among primates in...

The advent of hypervisors revolutionized the computing industry in terms of malware prevention and detection, secure virtual machine managers, and cloud resilience. However, this has resulted in a disjointed response to handling known threats...

This dissertation examines the behavioral and physiological adaptations employed by modern humans to subsist in tropical rainforests. I employ various theoretical and methodological approaches to test hypotheses using empirical data from African...

The first chapter of this thesis encompasses progress towards the X-ray structure determination and drug design for the dihydrofolate reductase-thymidylate synthase (DHFR-TS) enzyme from the protozoa Toxoplasma gondii, along with another mutant...

NAD+ is an essential co-enzyme for hydride transfer enzymes and a consumed substrate of multiple signaling enzymes including the sirtuins, a family of protein lysine deacetylases shown to regulate longevity in a wide array of organisms. We have...
